The recent Banana Pi BPI-F2S board features a new Arm SoC SP7021 by Sunplus, which is not yet supported in mainline Linux.

Multiple YAML schema files need to be added before I can submit this upstream.

Another thing to investigate will be how to boot Linux on the companion ARM9 core.

Looking for hackers with the skills:
